This study reports the synthesis and photoreduction of a complex featuring a tetravalent platinum center connected to a germyl ligand. In the presence of a chlorine trap, the complex undergoes a clean photolysis to produce two different products, which were confirmed and quantified using NMR spectroscopy and GC-MS analysis.
As part of our interest in the photochemistry of platinum/p-block element complexes, we now report on the synthesis and photoreduction of [(Ph)((o-Ph2P)C6H4)(2) GePtCl3] (2-Ph), a complex featuring a tetravalent platinum center connected to a germyl ligand. When in the presence of a chlorine trap, 2-Ph undergoes a clean photolysis that affords [(Ph)((o-Ph2P)C6H4)(2) GePtCl] (1-Ph) and [(Cl)((o-Ph2P)C6H4)(2)GePtCl] (1-C) as confirmed by NMR spectroscopy. While the formation of 1-Ph results from the elimination of a chlorine equivalent from 2-Ph, the formation of 1-Cl indicates chlorobenzene elimination, which was confirmed and quantified using GC-MS. These results provide a unique example of a germanium-centered light-induced reduction process resulting in the ipso-chlorination of a phenyl-germanium species.
